I've seen the renderings of this track. it's going to be INCREDIBLE when they finally complete it. I wish I could afford to attend the first F1 race there. I'm sure they'll pick up an INDY date and some bike races too.

This is the front straight looking up to turn one (which was the first pic).

This is from the end of the back straight. Which is just under a mile long. The grey area you see in the back is the beginning of the straight away. The surface undgulates and is has hills as well.to put it in perspective. When they hit this turn in an f1 car they'll be doing 220mph. Gp bikes about 200.

And this is the rendering. Hope you all see the awesomeness that is about to incur in Austin TX!
